It's based on : take a slow speed - you need quite a movement of surface to do as you wish .. increase speed significantly and that movement needed is far less. Now think of the poor old gyro - unless you link it's sense to throttle - you will have siimilar corrective output whatever speed by the gyro.
Just my 2c's worth ...
Thanks Nigel, that makes sense. Its easy enough to flick a switch and turn the gyro off when I'm moving quick and flick it back on for landing. I think I will do that next flight and see how it goes.
